Fig. 2 illustrates and includes tyre pressure sensor module 70 and electric power generation apparatus 72 according to embodiment
The simplified block diagram of integrated tire electronics product systems 22.The tire pressure sensing of electric power generation apparatus 72
Device module 70 and power regulation circuit 74 can enclose the wheel rim 40 being installed to wheel 32 (Fig. 1)
(Fig. 1) in the guard shield 76 on.Therefore, integrated tire electronics product systems 22 are contained in wheel
In the pressurized environment of tire 48.For the sake of simplicity, in conjunction with wheel 32 (Fig. 1) and integrated tire electronics

Solving, discussion below is equally applicable to integrated tire electronics product systems the 24th, the 26th, 28 and 62 (figure
1).
In general, electric power generation apparatus 72 and tyre pressure sensor module 70 are electrically interconnected thus to tire
Pressure sensor module 70 provides electric energy 78, is labeled as PWR.In addition, in certain embodiments,
Power generation blocks 72 can provide wake-up signal 80 to tyre pressure sensor module 70, is labeled as
WAKE.Tyre pressure sensor module 70 can sense the pressure of tire, processing pressure signal, and
Via antenna 84, output signal 82 is transferred to controller system 64 subsequently.Controller system 64
Including radio frequency (radio frequency, RF) receiver 86, this RF receiver 86 has antenna
88 for receiving the output signal 82 of transmission and output signal 82 being sent to information-processing circuit
90 carry out other process.Display 68 is connected to the output of information-processing circuit 90, and
Presenting at instrument board 66 (Fig. 1) place of vehicle 20 (Fig. 1) is derived by information-processing circuit 90
Information.
According to specific embodiment, electric power generation apparatus 72 includes the electric adjustment being positioned in shell 76
Circuit the 74th, flexible arm 92 and electric power generating element 94.Flexible arm 92 and electric power generating element 94
It is positioned at shell 76 outside.Electric power generating element 94 is coupled to flexible arm 92 and is configured to produce
Electric energy 78.More precisely, flexible arm 92 has the first end 96 and the second end 98.First end
96 are coupled to integrated tire electronics product via (such as) welding, edge connector, securing member etc.
The shell 76 of system 22.By the connection to shell 76, the first end 96 of flexible arm 92 is thus
It is coupled to the wheel rim 40 (Fig. 1) of wheel 32 (Fig. 1).
Second end 98 of flexible arm 92 is configured to the inside tread surface 100 with tire 48
Contact.But, the second end 98 mechanically decouples from internal tread surface 100.It is to say,
Do not exist and the second end 98 of flexible arm 92 is physically connected to the tight of internal tread surface 100
Firmware, adhesive etc..Owing to there is not the inside tread surface 100 to tire 48 for the flexible arm 92
Physical connection, therefore electric power generation apparatus 72 can decouple fully from tire 48.Correspondingly,
When needs re-type 48, including the integrated tire electronics product systems 22 of flexible arm 92 will be protected
Hold and be installed to wheel rim 40 without being replaced simultaneously.
In certain embodiments, the second end 98 include hook feature 99 or some other structures so that
In the second end 98 relative to the sliding motion of internal tread surface 100.For example, flexible arm 92
Can be prefabricated for or otherwise be shaped to include hook feature 99.Hook feature 99 upper
Turning over part can prevent the second end 98 of flexible arm 92 from adhering to or otherwise to a great extent
Damage internal tread surface 100.Those skilled in the art is it will be recognized that the second end 98 is permissible
Have contribute to the second end 98 relative to the sliding motion of internal tread surface 100 any properly
Shape.
Together with reference to Fig. 2 and 3, Fig. 3 illustrates facing of the flexible arm 92 of electric power generation apparatus 72
Figure.In an embodiment, flexible arm 92 presents the inner wheel at least corresponding to wheel rim 40 and tire 48
The total length 102 of the maximum magnitude of the distance between tire tread surface 100.Referring briefly to Fig. 6,
Big distance 104 is in the internal tire 48 of working as of tire 48 and does not connects with surface 106 (for example, road)
Touch and position when tire 48 is inflated sufficiently.
Referring back to Fig. 2 and 3, flexible arm 92 is by the material of the still elastically deformable of suitable rigidity
Formed.It is to say, flexible arm 92 is by can bend when being applied in power or the material of warpage is formed.
But, this deformation is reversible.So, once no longer apply to cause the power of bending, flexible arm
92 will be returned as its original shape.This type of material includes but is not limited to elastomer, shape memory gold
Genus, rubber etc..
In certain embodiments, flexible arm 92 includes surface 108, and this surface 108 has the first chi
Very little 109, for example, width (see Fig. 3), this first size is more than the second size 110, for example soft
The thickness (see Fig. 2) of property arm 92.This configuration of flexible arm 92 makes the flexible arm 92 can be greatly
Cause deformation on 112 on the direction of the flat surfaces 108 of flexible arm 92.Electric power generating element
94 surfaces 108 being coupled to flexible arm 92.More precisely, electric power generating element 94 is in flexibility
The position 114 that bend in arm 92 at utmost bends relative to the remainder of this bend
Flexible arm 92 is coupled at place.Although flexible arm 92 is described as having significantly greater than its thickness 110
Width 109, but in alternative embodiments, flexible arm 92 can have low width and thickness than
" whisker " configures.This type of " whisker " configuration can be used to so that the dismounting of tire is easier to, because of
Side load will be complied with for this configuration.
In operation, when wheel 32 rotates (that is, rolling), tire 48 and road 106
The part of surface instant contact is by immediate compression so that wheel rim 40 touches with the inside tire of tire 48
Distance between ground 100 reduces relative to ultimate range 104 (Fig. 6).Tire 48 and surface
Contact position between 106 is sometimes referred to as contact surface.As tire 48 continues to roll, this position
No longer contact movement with surface 106, i.e. contact surface terminates.Therefore, wheel rim 40 and tire
Distance between the inside tread surface 100 of 48 will increase to (such as) ultimate range 104.
This in response to distance between wheel rim 40 and tire 48 during this rolling of tire 48 is mobile can
